global $post;

$order = wc_get_order($post->ID);    

if(!empty($order) && $post->ID == $order->get_id()){
//do things
}

我知道我有一个具体的问题，所以我在搜索了几天后才回答。

Woocommerce拥有its own query 我决定重新使用：

public function pending_orders(){
        $query = array(
        \'status\' => \'on-hold\',
        \'limit\'=>-1
        );
        $pending_orders = wc_get_orders( $query );

        $found_variables = array();
        foreach ($pending_orders as $order){
          $foundit = array(
            \'id\' =>  $order->id,
            \'number\' => trim( str_replace( \'#\', \'\', $order->get_order_number() ) )
           );
           array_push($found_variables,$foundit);
        }
        return $found_variables;
      }

稍后，插件将查询付款：

public function search_haystack(){

        $pending_variables = $this->pending_orders();
        if (empty($pending_variables)){
            return;
        }
        $downloader = new Downloader($options[\'fio_token\']);
        $transactionList = $downloader->downloadSince(new \\DateTime(\'-1 week\'));
        $allTransactions = $transactionList->getTransactions();
        foreach ($allTransactions as $transaction) {
            if ($transaction->getAmount()>0){
                if($key = array_search($transaction->getVariableSymbol(), array_column($pending_variables, \'number\'))){
                    $this->maybe_complete_payment($pending_variables[$key][\'id\'],$transaction->getAmount(),$transaction->getCurrency());
                }
            }
        }
      }

public function maybe_complete_payment($variable,$paid_amount,$currency){
        $order = new WC_Order($variable);
        if (($order->get_total() == $paid_amount) and ($currency == $order->get_currency())){
          $order -> payment_complete();
          $order -> add_order_note(\'Successfully paired via Bank Transfer\');
        }
      }
